Question

An experiment involved six types of grass and four measurements of density per grass type. Here are some partial results. Fill in the empty blanks in the ANOVA table below. State f rounded to two decimal places. Source Grass Type Error Total df MS 200 2850 2. Using the data from Devore Ch 10, problem 4, complete the following steps. a. Calculate SST and SSTr, showing the formula in symbolic form, that formula with values filled in, and the result. b. Set up an ANOVA table as in Problem 1 with all values filled in. 3. Using MS-Excel, create a data summary table, similar to that in Table 10.1 for the data given on the assignment page. Make sure you set the MS Excel file up to calculate all values from the input data and label the values clearly 4. On the same MS Excel sheet for Problem 3, create an ANOVA table, as in Problem 2. Make sure all values are calculated by MS Excel from the table you created for Problem 3. Include a printout of the data table from Problem 3 and the ANOVA table from Problem 4 with your submission. Submit your MS Excel file to the Canvas drop box for this problem set.

Answer 1

1)

df_grass type = 6-1 = 5

df total = 4*6 -1 =23

SS = MS*df

F = MS grass type /MS Error

ANOVA
Source of Variation	SS	df	MS	F
Grass Type	1000	5	200	1.945945946
Error	1850	18	102.7777778
Total	2850	23
